i'm not sure how to configure wlan without passphrase, but below is a
netplan.yaml i use on all my pi's, just replace "your-ssid" and "your-
pssword", it will connect to your WLAN and also allow to plug in a
cable to use wired ... make sure ot get the indendation right, yaml is
very picky about this ... put the SD in your PC, mount it and place the
below file into /etc/netplan/ on the SD ... make sure it ends in .yaml
